Product Summary

The M27W401-80K6 is a low voltage 4 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). The M27W401-80K6 is ideally suited for microprocessor systems requiring large data or program storage and is organised as 524,288 by 8 bits. The M27W401-80K6 operates in the read mode with a supply voltage as low as 2.7V at –40 to 85°C temperature range. The decrease in operating power allows either a reduction of the size of the battery or an increase in the time between battery recharges.
